Weather occurs in the Troposphere layer of the atmosphere.

• True

• False

Which layer of the atmosphere extends to outer space?

• Stratosphere

• Mesosphere

• Exosphere

• Troposphere

• Thermosphere

What are the five layers that make up the atmosphere in order from outer space to the Earth's surface?

• Exosphere → troposphere → stratosphere → thermosphere mesosphere

• Troposphere → stratosphere → mesosphere → thermosphere → exosphere

• Exosphere, Thermosphere → Mesosphere → Stratosphere → Troposphere

• Troposphere mesosphere → stratosphere exosphere → thermosphere

As air gets colder...

• Air pressure decreases

• Air pressure increases

• Air pressure stays the same

• Air pressure changes depending on the time of year

Which of the following processes is where water from the Earth's surface is converted from a liquid to a gas (water vapor)?

• Precipitation

• Runoff

• Condensation

• Evaporation

• Transpiration

Which of the following processes is responsible for the formation of clouds in the atmosphere?

• Precipitation

• Runoff

• Condensation

• Evaporation

• Transpiration

One important part of the water cycle is missing from the figure below. Without this feature, the water cycle could not happen. What is it?

• Evaporation

• The moon

• The sun

• Rain and/or snow

• Ocean tides

Which explains why most of the rain that falls comes from the ocean?

• The majority of evaporation takes place over the ocean.

• The majority of precipitation takes place over the ocean.

• Most rivers deposit freshwater into the ocean.

• Most clouds form near or over the ocean.

Differences in air pressure most directly cause which of the following?

• Earth's winds and weather changes

• The water cycle

• Air pollution

• Clouds

What conditions are necessary for all forms of extreme weather?

• The moving of a front, high pressure system, no winds

• The moving of a front, low pressure system, no winds

• No fronts nearby, high pressure system, high winds

• The moving of a front, low pressure system, high winds
